DIY Smoke Machine For Vacuum or EVAP Leaks E46 P0171 P0174

In this video I show you how I constructed my own DIY Smoke Machine out of a paint can, a propane regulator, tiki torch wicks, and some Kanthal wire. This is the same smoke tester that you can buy on eBay for $100. I think I put about $30 into it. I then show you how to perform a smoke test and what a couple different vacuum leaks would look like on an E46 BMW.
